Question

So currently I am using a 3rd party software application to get results from various surveys. This application is sending the results to a page via a $_POST variable.

So for example..

$demoEMP = $_POST['demoEMP'];

This just stores the answer from the specific question into a variable.

What I want to do is store Questions 1-20 in POST variables and Insert them into a database..
What I don’t want to do is write 20+ Insert commands or 20+ $var = $_POST[‘var’]

So I was thinking a for loop would do the trick… This is what I have so far… based on looking at various methods and tutorials. =/

for ($i = 0; $i < 55; $i++) {
$answer = "Q{$i}";
echo $_POST[$answer];
}

Am I even on the right track? Thanks for your help!

UPDATE::
Kas’ solution worked great.

I used something like this…

foreach ($_POST as $i => $v)
{
if (preg_match("/^Q\d+$/",$i)) {

// Here we insert value $v to database
$query_2 = mysql_query("INSERT INTO SGresult VALUES ('', '', '$pID', '$SGQID','$v')") or die('Error: '.mysql_error ());

}
}

However, I am now trying to figure a way to add an ID to the question and have that ID auto increment… on every insert. I thought I could do something like $SGQID++ but that does not seem to be working.. anyone have any thoughts?

Thanks again!

okay after some more tinkering it seems the placement of the ++ was off and it needed to be after the query… the correct code is as follows.

$SGQID= 1;

foreach ($_POST as $i => $v)
{

if (preg_match("/^Q\d+$/",$i)) {

// Here we insert value $v to database
$query_2 = mysql_query("INSERT INTO SGresult VALUES ('', '', '$pID', '$SGQID','$v')") or die('Error: '.mysql_error ());
$SGQID++; //added value to increment Question ID in DB

}
}

foreach ($_POST as $i => $v) {
  if (preg_match("/^Q\d+$/",$i)) {
    // Here we insert value $v to database
  }
}
